To alt wlw/n may conce/11n.'

Be it known that we, JOHN S. THOMPSON and Josemi Bisi', citizens of the United titates, residing at Chicago, in the county of Cool: an( State of illinois, have invented new and useful improvements in Machines for (fasting, oiI whichthe following a full, clear, concise, and exact description, reference being had to the accompanying drawing, iorniing;l a part ot this specification.

Our invention relates to improvements in machines for castingV continuous` strips of material for use in the printing' art, which strips are cast in a series ot sections or molds. each section or mold fusing with the next preceding east in order to make one continuons strip.

One oit the objects ot' our invention is to pro'fv'ide a. machine which shall cast the sections that the tus-ing' of the sections tol( rether will be acernnplished in a more satisfactory manner. Another object of our invention is to provide means for cutting the strips into predetermined lengths. For the purpose ei' disclosing our invention, we have illustrated in the accompanying' drawings one ot the embodiments thereof. in said drawings Figure l is a side elevation of a machine embodying our invention, partially in section;

Figli 1i is a sectional View on the line ii-ii er ing. i.

'in the machine illustrated, we provide support l, ot anyy chan acter, on which is mounted themold and other parts oi2 the maohine. This mold in the present instance consists, respectively, ot the two mold blocks S2 and 3, the vertical faces ot which tit closelyv together, being held together hy the holts or Screws fi. The liloclc 2 intermediate of its top and bottom is channeled out, as at el, to receive the pusher plate or pusher member 5. The front portion ot the block .is recessed, as at 6, to receive the mold block 'I'. rihis block consists, as shown in Fig, sl, ot a solid hlock et metal having extending along its front tace a channel or mold. cavity 8. The block has a laterally extending flange 9 which fits over the side block 2 and which comprises a means for suitably holting the mold block .in position. The mold cavitjv7 8 terms the cavity in which the molten metal is toi-ced,`

anchas it will he seen, is open `from end to end. A portion of the mold block 'l' abuts 'up against the lat tace ot the sidev hloclr se that this itat tace forms one wall of a portion ot' the mold cavity. This block vis removably mounted in position in order that it may he changed, the mold blocks havingr different sized and shaped mold cavities so that different sized and shaped mold cavities may he substituted, due to the removahility oit the hlocls, for the one illustrated. The front face 10 or" the side hloclv'` 3 is .recessed to form a jet opening 1l.. rihis jet opening as shown in Fig. 2 is substantially li-shaped, the nai'- row portion ot the opening being toward the jet nozzle and the wider portion opening into the mold cavity 8. lit thecentrai portien there is provided a small lll-shaped or other shaped spreader l2, tor spreading the molten metal as it is `forced through. the jet opening. In front of the opening and adjacent the block 3 is a jet block 13 in which tits the nozzle i4 through which the molten metal is t'oiced, this nozzle connect ine' with the mollen metal port- 15. Vertr cally m ,\\'al le along that portion ot the mold cavity 8 not covered hy the side hloek FS is a reciprocating; cover i6, which dui'.`- ing the molding operation is raised and covers the exposed portion of the mold cavity 2%, and which during the moving period ot operation ot` the. machine is lowered to permitthe passage of the 'jet casting 17 formed on the strip. This cover is mounted upon a reciprocating member i8, which is driven hy a lever i9 operating from .suitable cam mechanism. After each Cast is made, the cast is forced out ot' the mold cavity S by means ot the body piece 20, which is removably connected with the pusher 1nen1ber This body piece is otl the same width and thickness as the nlold ca"ity lH and reciprocates therein. In tact, the rear end ot this body piece forms one wall ot the mold cavity. The rear end ot the body piece is provided with a pair of notches` 21, whereby a restricted neck Q2 is formed therein. This neck fits -in a notch t'ormed between a pair ot lugs 223 on the side face ot' the pusher member 5 and the,

rear end 2t ot the body piece lies in a suitable recess 25 in the pusher member. This recess 1s. as shown,'stepped 111 depth, so

.that in the event a thicker or deeper body piece is used` the rear end is shortened and will tit down in the deeper portion 2G ot' the recess. The rear end oi the pusher member 5 is connected by connecting rod 2T with a vrocking arm 2H driven with a bell crank arm 2S, the opposite end oit which is geared, as at 2f), and is adapted to mesh with a suitable driving gear so that the arm will be operated to reciprocate thel pusher mein` ber lThe rear end of the rod ZT is pivotally connected with a bolt 2T, passing through the arm 28 and ha ving on itsl end a thumbnut 27C, between which and the arm 28 is mounted a coiled spring 27d. The rod 2T also passes through a stop 2T" which is secured to the frame by screws 2'1"t passing through slots 27K in the horizontal arin 2T ot' the stop Q7 and into the traine of the machine. The rcar ond ol they pusher member 5 strikes against the stop 2T" and its stroke is limited thereby,

Thus. by adjusting the stop 27e,

the length of the casting may be varied. By providing the resilient connection between the arnrifs and the holt Q7", the pusher member, and with it. the body piece 20, may be stopped at any point by the stop 27 and without the necessity oi varying the, adjustment or varying the throw oi' the arm 28,

. It will be noted thaty the mold cavity is so arranged that the, side thereof is at' right angles to the jet opening, so that. the molten metal is forced into the cavity at an angle to the width ot' the cavity internndian` the edge walls thereof. Bv this arrangement the molten metal will more quickly eonie in contact with the edge ot the rast' previously made, tending to nielt thisl edge and cause the two sections to fuse together, We have found from experience that where the inetal is introduced into the inold cavity from what might be termed the edge thereof, the molten metal in tiowing along the edge ot'v tlul previous cast is chilled begtore it getsl to the com plete end of its inoveineirt'a-u'(t that the eon1- plete fusing of the metal-is not apt to reault,

, 111g carried forward with the cast,

In operation of the machine, we will assuine that one cast has been made and that the same has been pushed until it is in the position illustrated in F ig. of the drawing, that is, it is in a position where its rear edge is slightly beyond the front edge of the block 3, so that the jet cavity 1l communicates with the mold cavity S; the cover plate 16 1s raised in its position to hold the cast flat in a forward portion ot' the mold cavity and the body piece 90 is retracted to the. extreme rcari 'ard movement; Of its stroke, leaving the mold cavity open; the hotmolten metal is pumped from the pot through the nozzle 1i and passes through the jet cavity into the mold cavity, the metal being spread and deflected by the. detleetor 1Q in the jet cavity.

1t will be seen that the rear edge of the prcceding cast forms a front wall of thel niold ately sets and the cover plate 1.6 moves downward to a point below the bottom ot' the mold cavity, rlhe body piece then cour nienees its forward movement and the cast thus made is moved forward, the jet cast be- As soon as the body piece has moved to the forward liinit ot its stroke, it commences its return movement, and at the same time the. cover plate nieves up so that by the time the body piece has reached its rearward end of the stroke, the parts are in position for another cast. l

lThe jet piece 17 may be removed in any desired manner, 011e, way of removing the saine is accomplished by providing a stat'ionary knife 30 against which it, is forced during the toi-ward progress of thecast strip and which shears it off ot the strip.

The strip rast is cut oit' in ydefinite lengths h v meansI oi the cutter at the right-hand end o1" the machine, This cutter connirises :1 movable blade 31 operating against a knifeedge 32. and between which the strip is adapted to pass as it 'feeds out of the casting mold. Yllhe movable blade is pivotcd at 33 on a suitable supporting block Si. which. together with the receiving pan v'tor the strips. is secured to the traine ot the ma- 'l`he upper end ot' the blade has pivoted thereto a striking dog 36. by which the kiiile is rocked on its pivot P13 in a direction to shear the strip. For operating the knife l provide an operating lever 31' pivoted at 23H to the traine and having at its lower end eastino-` roxnprisin.:

nee-etre same, movingi the knife toward theI cuttingedge 32 to malte the shear, the knife being returned to normal position ihy a'springil bearing thereon above its pivot point. This dog 36 is held in its raised position hy means ot' a cam Lll, preferably taking the form of Aa wire traine,y the upper end of which is inclined, as. shown, to form a cam surface, and mounted on a reciprocating rod l2. rlhis rod is provided with an adjustable finger i3 adapted to he engaged bmv the end. ot' the strip as it feeds out trom the machine; rlhe rod at its rear end is secured to a crossmember -l-l. which is also connected to a rod l5 and 'held in its retracted position hy means et' a coiled spring i6 interposed hetween a stationary collar el? on the. rod and the support 48. i

in operation, the length ot' casting to he made is set by the stop 27,and thisi to gether with the linger 43, which may he adjust-ed to various positions, determines the length oit the strip to be cut. The linger l2- being placed at the desired point, as the strip t'eeds ont from the mold one end eventuallyY strikes this linger, forcing the same back and carrying with it the cam ll, which allows the dog 36 to drop in the path ot' the arm 25T. and as the cam l0 moves the arm 3T to the innermost, position thiring) the molding` operation, the dog' 36 and the blade 31 will he moved Yto shear the strip during the interval when the strip isat rest While an additional casting is being made. At the same time that the knife 3l is rocked on its pivot, the kicker i9? mounted on a pair of arms 5G, one. ot' which is pivoted to the Support. t8 and the other secured to the pivot 32- to rock therewith, will hielt-the sheared strip ont into the pan 35.

The kicker #lv-9 is provided with a hoolishapod guide lila which engages over the 'top of the metal strip during' its tor fard more ment to 'hold it in upright position` and a rod 49 connects thc two arms 50 together.
